Undecided questionsHow does one use について?

I know that についてmeans "about", but I'm not sure how to use it in a sentence. For example, could use it if I wanted to say, "I have a lot of questions about school"? Does it mean anything else or have certain connotations? Thanks much!

As Atsumi told you, について works perfect on the usage of that "about" and no connotation at all. At least at a learning stage you can definitely use it every time when you translate the "about" into Japanese.
